D. C How many unpaired electrons are found in the ground state electron configuration of selenium (Se)? Paramagnetism is a form of magnetism whereby certain materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. In conductive materials, the electrons are delocalized, that is, they travel through the solid more or less as free electrons. If there are no unpaired electrons, there will be no attraction to an applied magnetic field (diamagnetic). Diamagnetic substances are characterized by paired electrons, e.g., no unpaired electrons. , the additional energy per electron from the interaction between an electron spin and the magnetic field is given by: where Legal. Pauli paramagnetism and Landau diamagnetism are essentially applications of the spin and the free electron model, the first is due to intrinsic spin of electrons; the second is due to their orbital motion.[5][6]. It is not uncommon to call such materials 'paramagnets', when referring to their paramagnetic behavior above their Curie or Nel-points, particularly if such temperatures are very low or have never been properly measured. If there is sufficient energy exchange between neighbouring dipoles, they will interact, and may spontaneously align or anti-align and form magnetic domains, resulting in ferromagnetism (permanent magnets) or antiferromagnetism, respectively.
